Gronkowski, 24, listed his waterfront estate in the Westshore Yacht Club last week for $2.4 million. The All-Pro tight end bought the home last August for $1.6 million.

The gated three-story mansion boasts a wood-paneled elevator, custom-built fish tanks and a casino-style security system. The 4,700-square-foot home comes fully furnished and includes two Yamaha personal watercraft.

Gronkowski chose to sell the home because he "was not able to visit Tampa enough to enjoy the property," listing agent Michael Palermo said.

"His commitments to the Patriots and his sponsors took up more time during the off-season than he had anticipated," he said. "The demands on his time are not expected to change in the near future, so he decided to sell."

Though his time at Chez Gronk was short, Gronkowski made a number of improvements to the home, Palermo said. He paid for new air-conditioning systems, a crisp paint job, a personal-watercraft lift in the backyard boat slip and a remote-control system for the pool and spa.

Gronkowski bought the Beacon Shores Street home two months after signing a six-year, $54 million contract extension with the Patriots last year. As part of the deal, the sellers included a 26-foot Caravelle Bowrider powerboat, which Palermo said has since been sold.

As to whether Gronkowski is in the market to buy another home? "Not that I am aware of," Palermo said.
